Sang Keun Choe

Background

I am a first-year CS PhD student in Language Technologies Institute at Carnegie Mellon University, and fortunate to be advised by Prof. Eric Xing. Previously, I completed my MS in computer science at CMU under the guidance of Prof. Jaime Carbonell. Prior to CMU, I earned BS in Electrical Engineering and Mathematics from Seoul National University.

My research interests are broadly in neural networks optimization, and large-scale distributed machine learning.
